In the now broad field of human dental genetics, variations in the number of permanent teeth have attracted repeated attention. Indeed, of articles dealing with population frequencies, pedigree analysis, or estimates of hereditability, the greatest number have been concerned with missing or supernumerary teeth.'-4 It is not difficult to understand why such tooth number polymorphisms have preemp...

talon cusp is an accessory cusp similar to a projection, extending from the cingulum or cemento-enamel junction to the incisal edge. it occurs on labial or palatal surfaces of primary or permanent anterior teeth in both arches. this accessory cusp can occur as an isolated entity or in association with other dental anomalies. occurrence of a talon cusp on supernumerary teeth is rare and uncommon...

Taurodontism is a tooth anomaly characterized by an enlarged pulp chamber and an apical displacement of the pulpal floor. It ́s more prevalent in molar teeth, with few cases reported in premolars. Objective: To describe bilateral taurodontism in lower premolars associated with supernumerary teeth in a young patient. Case report: 10-year old female patient evaluated in a routine appointment. Clin...

Fusion of teeth is the union of two or more tooth germs, which are usually separated. Depending upon the stage of odontogenesis, it can be complete or incomplete. The present case describes fusion between the maxillary primary right central and lateral incisor with a supernumerary tooth. Clinical and radiographic examination revealed the presence of fused triple teeth. The fused teeth were extr...

BACKGROUND Mesiodens is the most common type of supernumerary tooth found in the premaxilla. It might be discovered by the clinical examination by chance on a radiograph or as the cause of an unerupted maxillary central incisor. The genetic transmission of supernumerary and impacted teeth is poorly understood. Mirror imaging in twins has been reported frequently in relation to several unilatera...

A review of the literature relating to supernumerary teeth is presented along with four case reports to illustrate some possible presentations, diagnostic features,and treatment options.
